Gengar is a Pokémon that is weak to certain types of moves. It is a Ghost/Poison type Pokémon, which makes it vulnerable to certain types of attacks that are super effective against these typings. Here are the types of moves that are particularly effective against Gengar:

1. Dark Type Moves: Being a Ghost type Pokémon, Gengar is weak to Dark type moves. Dark type moves such as Crunch, Knock Off, and Dark Pulse deal double damage to Gengar.

2. Psychic Type Moves: Gengar's Poison typing makes it weak to Psychic type moves. Psychic type moves such as Psychic, Psybeam, and Psyshock can deal super effective damage against Gengar.

3. Ground Type Moves: As a Poison type Pokémon, Gengar is also weak to Ground type moves. Ground type moves such as Earthquake, Earth Power, and Dig can deal significant damage to Gengar.

4. Ghost Type Moves: While Gengar is immune to Normal and Fighting type moves due to its Ghost typing, it is still vulnerable to other Ghost type moves. Ghost type moves such as Shadow Ball and Shadow Punch can deal super effective damage against Gengar.

It is important to note that Gengar's weaknesses can be mitigated by its movepool, ability, and held items, so these weaknesses may not always guarantee a swift defeat.
